Bambance-bambance tsakanin PWM & MPPT
PWM: Maganin Pulse-Nisa
MPPT: Matsakaicin Binciken Wutar Wuta
PWM da MPPT nau'ikan nau'ikan hanyoyin caji iri biyu ne masu kula da cajin hasken rana zasu iya amfani da su don cajin batura daga tsarar rana/panel. Dukansu fasahohin ana amfani da su sosai a cikin masana'antar hasken rana kuma duka manyan zaɓuka ne don yin cajin baturi da kyau. Shawarar yin amfani da ƙa'idar PWM ko MPPT ba ta dogara ne kawai akan wace hanyar cajin wutar lantarki ta “mafi kyau” fiye da ɗayan ba. Bugu da ƙari, ya ƙunshi ƙayyade nau'in mai sarrafawa zai yi aiki mafi kyau a ƙirar tsarin ku. Don fahimtar bambanci tsakanin cajin PWM da MPPT, bari mu fara duban yanayin wutar lantarki na PV panel. Ƙarfin wutar lantarki yana da mahimmanci saboda yana bayyana ƙarfin da ake tsammani na panel bisa ga haɗin haɗin voltage ("V") da na yanzu ("I") da panel ɗin ya samar. Mafi kyawun rabo na halin yanzu zuwa voltage don samar da mafi yawan iko ana kiransa "Maximum Power Point" (MPPT). MPPT zai canza da ƙarfi a cikin yini dangane da yanayin iska.
- Mafi sau da yawa zaka iya samun lanƙwan wuta don panel PV ɗinku akan takaddar bayanan samfurin.
PWM Masu Gudanar da Cajin
Modulation Pulse-Width (PWM) yana zuwa cikin wasa lokacin da bankin baturi ya cika. Yayin caji, mai sarrafawa yana ba da damar yawan halin yanzu kamar yadda PV panel/array zai iya samarwa don isa ga maƙasudin manufa.tage don cajin stage mai sarrafawa yana ciki. Da zarar baturi ya kusanci wannan manufa voltage, mai kula da caji da sauri yana canzawa tsakanin haɗa bankin baturi zuwa tsarin panel da kuma cire haɗin bankin baturi, wanda ke daidaita ƙarfin baturi.tage rike shi akai-akai. Wannan saurin sauyawa ana kiransa PWM kuma yana tabbatar da cajin bankin baturin ku da kyau yayin da yake kare shi daga yin caji da yawa ta hanyar PV panel/array.
Masu kula da PWM za su yi aiki kusa da iyakar wutar lantarki amma sau da yawa dan kadan "sama da shi". ExampAna nuna kewayon aiki a ƙasa.

Matsakaicin Binciken Wutar Wuta yana da alaƙa kai tsaye tsakanin tsararrun PV da bankin baturi. Haɗin kai tsaye ya haɗa da DC/DC voltage Converter wanda zai iya ɗaukar wuce haddi PV voltage kuma canza shi zuwa ƙarin halin yanzu a ƙaramin voltage ba tare da rasa iko ba.
Masu kula da MPPT suna yin wannan ta hanyar daidaitawar algorithm wanda ke biye da matsakaicin ƙarfin wutar lantarki na tsararrun PV sannan kuma daidaita vol mai shigowa.tage don kula da mafi kyawun adadin wutar lantarki don tsarin.
